Whitehat Yash Sodha submitted a critical vulnerability in Bitswift to Immunefi. The race condition vulnerability would have allowed a malicious user to repeatedly claim the same voucher, which entitles a user to some amount of crypto tokens. In summary, a hacker could have potentially sent high frequency claim requests in parallel to Bitswift’s claim faucet and received more crypto-assets than the hacker was entitled to. This vulnerability was not exploited. Bitswift disabled the claim faucet function and immediately worked to implement a fix. Bitswift paid a $5,710 CAD bounty to the whitehat for disclosing the vulnerability.
